Frequently Asked Questions
How much will my PDF be compressed?
Typical compression is 40โ90% size reduction. The exact result depends on content โ image-heavy PDFs compress most, text-only PDFs compress less.
Will compression affect text readability?
No. Text in PDFs is stored as vector data, so text sharpness is always preserved. Images may slightly reduce in quality but remain excellent for screen viewing.
Can I compress a password-protected PDF?
You'll need to unlock the PDF first using our free Unlock PDF tool, then compress the resulting file.
Why does my PDF look the same size after compression?
Some PDFs are already optimized or contain only non-compressible data (like pre-compressed JPEGs). In those cases, further size reduction is minimal.
